The body of the Fox Nation post is merely a listing of Gallup's latest tracking poll results of Obama's approval and disapproval. Fox accurately describes his approval at 49% (at the time, it has since risen more and is now at 51%) and his disapproval at 45%. But if you click on the link right there in Fox's post, you'll see for yourself that those approval numbers are going up, not down, and have been since November, 2011.

Also worth noting is the fact that other polls show much higher approval for the President, with even right-leaning Rasmussen showing Obama at 55% approval.
